WPF 圖表控件 MetroChart_.NET_编程开发_程序员俱乐部

Torsten Mandelkow MetroChart包括以下：

• ColumnChart（ClusteredColumnChart，StackedColumnChart，StackedColumnChart100Percent）
• 饼图（饼图和Dognut）
• BarChart（ClusteredBarChart，StackedBarChart，StackedBarChart100Percent）
• 甜甜圈图
• 径向测量图

有相当大的演示可以从CodePlex下载，但是不夠詳細的，所以我决定写一个小的入门指南。作为文档的一部分，还有一个操作方法，但它并没有真正起作用。图表没有渲染，我一步一步地遵循了如何操作，

其中

• ChartTitle是图表的主要标题
• ChartSubTitle是字幕，当然以较小的字体显示
• DisplayMember是保存该值名称的属性的名称
• ValueMember是保存该值的属性的名称
• ItemsSource是本系列产品的来源。
• SeriesTitle拥有特定系列的标题
